“On the tenth floor I was admitted by a uniformed female who took my hat and coat, put them in a closet, and conducted me through an arch into a room even bigger than Lily Rowan’s where twenty couples can dance. I have a test for people with rooms that big–not the rugs or the furniture or the drapes, but the pictures on the walls. If I can tell what they are, okay. If all I can do is guess, look out; these people will bear watching.”
Rex Stout, The Doorbell Rang
